Solved

HI Guys,Sorry to bother you... Now I was working use STM32C0XX series chips, my development tools is IAR8.50, and find that IAR8.50 can't show STM32C0XX series chip, I had check some data: someone said should upgrade IAR FW, others said I should add STM32C0XX Lib config files into IAR development, but I can not find where I can download STM32C0XX config lib, so what should I do? 

Hello im Khoi. i get big trouble with stm32l431rct, when i using freeRtos . Task1 i using spi comunication . Task2 i get ADC DMA . When i disable Task2 program no problem. But i enable task2 get problem spi hardfault-Handler . Excuse me :(( 

Hello ST experts I found the same problem as previous post  https://community.st.com/t5/stm32-mcus-embedded-software/stm32f072xb-gpio-issue-usb-pins-do-not-work-as-gpio/m-p/151104#M8715  But for stm32u595, I can not find the similar register USB_CNTR.PDWN. Is there any way to set PA12 as GPIO input? Best RegardsYang

The error occurs when I try to run the code generated for model squeezenetv1.1_xxx_tfs_int8.tflite The command I used to generate code is stm32ai generate -m squeezenetv1.1_128_tfs_int8.tflite -O ramAnd I follow the guide "How to run locally a c-model" in the X-CUBE-AI Documentation to get the executable.When I run the elf, it returns an assertion failed which like this.Assertion failed: (((ai_size)(ai_array_get_byte_size(((ai_array_format)(((ai_array*)(p_tensor_scratch->data))->format)), (((ai_array*)(p_tensor_scratch->data))->size)))) == scratch_size), function ai_layer_check_scratch_size, file layers.c, line 289.To figure it out, I observe the intermediate output per layer following the guide "Platform Observer API" in the X-CUBE-AI Documentation.And I find out that stm32ai generates the wrong size for the scratch data of one Conv2D layer.          The correct shape should be (1, 63, 63, 64), but

The error occurs in both Mac m1 and windows. When I use "stm32ai validate/generate" command, I find that "-O ram" outputs totally strange results. Let's use fdmobilenet_0.25_224_tfs_int8.tflite from stm32ai-modelzoo as an example. "stm32ai validate -O time/balanced fdmobilenet_0.25_224_tfs_int8.tflite" outputs as belowThe "X-cross #1" here is 100% which is perfect, but for "stm32ai validate -O ram fdmobilenet_0.25_224_tfs_int8.tflite", something strange happens.The "X-cross #1" is 10% and the accuracy of c-model is 0% meaning that the model can hardly do what the developers want to do. Note that this happens in about 30% models for image classification in stm32ai-modelzoo as I tested.To get a rough reason for this problem, I observer the intermediate output per layer between "-O ram" and "-O time/balanced". I find that, for only fdmobilenet_0.25_224_tfs_int8.tflite, the difference first happened in a "conv2D + maxpool" layer. In "-O ram", it is fused

Hi during development of program I found weird behaviour. I am using STM32G030C8T6 MCU. I am trying to connect external device using HC-05 bluetooth module. In my project I also connect with devices using MAX3485 module for RS485 communication. I wrote python app on laptop to send information to my MCU. Information is interpreted in MCU and then it answers with same information to external device to ensure correctness of communication. Everything worked well until I started to listening for response from RS485 devices. Somehow request for connection and then first request from laptop, before sending any data to RS485 devices, works as desired, but after that any data obtained from MCU is seen on laptop as 0x0b in hexadecimal. I only send one byte of information in bluetooth communication. First I thought that maybe there is a problem with priority of interrupts but then I changed NVIC settings for UARTs in .ioc file for 1 for RS485 and 0 for bluetooth and nothing changed. Also weird is

Hello,I have a circuit which uses the L6470 with a STM32F401.  I based the circuit off of the development board, X-NUCLEO-IHM02A1 which has 2 L6470's on board.  https://www.st.com/en/ecosystems/x-nucleo-ihm02a1.htmlThe X-NUCLEO-IHM02A1 circuit has a large cap on VS.  The documentation on the X-NUCLEO-IHM02A1 states the power supply can be between 8 and 45 V.  Our circuit is to be used at 24VDC.  The large cap on the X-NUCLEO-IHM02A1 (C7 and C23) is listed as 100uF and 63V.  On my design, I am using 100uF 50VDC.  We built some units and supposedly the units were in service for a period of time but then at some point failed.  I received two boards back that show damage to the L6470 and the large cap that would be on VS to ground.  The L6470's show burn marks on the top of the chip and on board the large electrolytic cap was blown off of the board.  When I checked the cap for resistance it read nearly a short (just a couple ohms).  On

I got this from github.  It compiles ok.  The package has source for STM32WLxx_HAL_Driver.  How can I find out what version is the STM32WLxx_HAL_Driver?  TIA  

I am using CAN1 pins to Connect to the driver board (SN65HVD230).     All Voltages are good. I am using 2 PCAN dongles with 120 Ohm terminations at both ends of the BUS with the Nucleo CAN shown above in the middle of the bus.  I ported the code from the following project;   >TX Mailbox used: 0x1t>TX Mailbox used: 0x2s>MCR: 0x30Can State: 0x2Interrupts: 0x1007F, msr flags: 0xC00 , tsr flags: 0x52000000, rf0r flags: 0x0, rf1r flags: 0x0, esr flags: 0x0 The Tx message is not getting out.   Also I have a PCAN message being transmitted on one PCAN dongle and the other PCAN Dongle is receiving the message fine.     The Nucleo pcb does not see the message at all. I am using the default clock setup for the NUCLEO board       void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ __HAL_RCC_PWR_CLK

Hi,Some doubts on the ECC functionality on STm32h74x.How can we know if the data can be corrected for cases DEDF and DEBWDF ? I always see the DEDF and SEDF fields set in my case. This bits are set when the control is hit the main(), and then I cleared it forcefully by writing 0x03 to M3SR and M4SR (when the control is at the red line). But, these bits were set immediately when I stepped into the next instruction (see below snapshot). Why is this so ? 

Hi, Does myir MYD-YF135 development board support Bare Metal Project?

Hello,I am using a STM32G491 in LQFP48 package. In the RM0440 rev8 page 2122 the package code for LQFP48 is 01011. But I read 01001 which would be LQFP32. The device id 0x479 is correct. Is there a reason for this? Thanks.

Hello,I have a custom H743 board with Microchip USB3340 external PHY (REFCLK = 24MHz, dedicated external oscillator)In an code that use ChibiOS, my configuration should achieve HS mode, but ultimately, after handshake, it revert to FS mode (12Mbits/s) : so it works, but it is slow.In order to understand where I am wrong, I have flashed STM32F7Cube(V1.17.1)/STM32746G-Discovery/Applications/USB_Device/MSC_Standalone/SW4STM32/STM32746G-DISCOVERY_USBD-HS on a discovery F746, but problem is same : when plugged on a computer (tried several : windows and linux, different usb cables) official ST MSC HS demo connect in FS mode, not HS mode with same symptoms : slow transfert rate.Can some someone can point me a working MSC HS demo, or has clues why ST demo don't do HS, and if there is a way to fix that ?ThanksAlexandre

Hello everyone,I need to get some information about the power consumption of the STM32 Nucleo-64 with STM32F401RE MCU.The board is powered from the computer's USB port.The board has a IDD jumper (JP6) for MCU current measurement so I attached a Parkside multimeter to get the current.I created a project in which the main while loop is empty and all peripherals are disabled. In this case, the current shown on the display of the multimeter is fixed.If I modify the project and I use the timer interrupts to acquire data from the sensors, the current shown is fixed. If I create another project without interrupts but acquiring data from the sensors in the main while loop, the current shown is fixed. If I add some "printf" (using USART2 and PuTTY) to show these data, the current is variable. If I create a project in which I execute some inferences of a neural network, the current is variable.Why do I have a fixed value of the current on the display in some cases and a variable value

I'm working with a legacy project that uses some EEPROM emulation code on a STM32F103 MCU. I need to find the original release file containing eeprom.c and eeprom.h of that emulation code. The description of the header file looks like this:  /******************** (C) COPYRIGHT 2008 STMicroelectronics ******************** * File Name : eeprom.h * Author : MCD Application Team * Version : V2.0.0 * Date : 06/16/2008 * Description : This file contains all the functions prototypes for the * EEPROM emulation firmware library. ********************************************************************************  As you can see this is very old code. Is there a place where I can find the original release package that contained these files?I was able to find similar, much newer code but not that exact release/version.Thanks a lot!

HelloI have been trying to develop a GUI App to communicate with STEVAL-25R3916BA to read & write ISO15693 Tag Type-V. So far with reference from similar other questions asked previously on this forum I have been able to connect to EVAL board and at least read UID of the tag. This I was able to achieve thanks to response from @Ulysses HERNIOSUS responses. To achieve this I have used the example application comes with ST25PC-NFC & ST25 SDK. The example project from ST. for C# does not have read/write example, I have tried my best to perform read/write using APIs from ST25R3916DISCOComm DLL, but so far no success, APIs comes back with no error & no data, if there is no error then why no data? I am trying to use iso15693ReadBlock & iso15693WriteBlock from DLL, and I have used ST25PC-NFC to write 0xFF to whole memory of Tag type-V, so I know what I'm reading is okay, as currently API for reading just reads 0 with no error! So I'm not

Hi,I'm using P-Nucleo-VL53L8A1 multi-zone time of flight sensors for smoke detection in the open air.I've seen STSW-img043 MZAI_EVK_v1.0.1 for calibration and recording sensor data of VL53L8CH.I would like to know what is the best Machine learning method (ANN, CNN or ...) for training a reliable model with small footprint for STM32WLE series.Does STMicroelectronics support ready to go example for building and training an ML model for classification of VL53L8CH data?Which tools should be used to convert the model to a c library for embedding the ML model in the MCU? Thanks.

Hi, I've imported the LwIP_HTTP_Server_Netconn_RTOS example into a new workspace I created but I'm unsure how to build and launch it and there doesn't appear to be an *.ioc file where I can select/verify the pin for my F439ZI MCU. Where can I find instructions to build and load the project?

As customer's request, can we have the latest SGS report for parts: ST:L3GD20H & ST:LSM303AGR?

Is there a .NET SDK for ST25 NFC tags that will let me read and write ISO 15693 Type 5 tags in C#? I have the ST25R3911B-DISCO reader/writer board.The closest I've found so far is a COMMS dll which appears to be taken from the demo app and will not load under 64-bit .NET. I've also seen the Java SDK but that looks like it is using the same DLL under the covers and is again 32-bit only, so I can't use it in my 64-bit app.I would ideally like to be able to use these tags from a modern (.net 8 64-bit) app. Any suggestions appreciated.

Because there appear to be little/no stock of the STM32U535CEU (QFN Version) I'm left with a dilemma of whether to use the built in SMPS.  Some documentation in another post describes how to connect up when not using it but how do you switch between using the LDO and the SMPS?  I can't see any options in the CUBE IDE .ioc file...

Hi eveyone,I have a problem with RTC wake up. I use LSE 32.768kHz.I run example from manufacturer to wake up MCU from Stand by mode very 1min, 2mins. Everything work okay.But, When I put delay 10s and HAL_PWR_EnterSTANDBYMode(); into while(1). Everything is not okay.The RTC does not wake up on time, when I delay 10s it will lack of 10s, when I delay 20s it lack of 20s. I try to do it many times.How can I wake-up mcu on time in time I set?Thank you for any help.int main(void) { HAL_Init();   /* Configure LED3 */ BSP_LED_Init(LED3);   /* Configure the system clock to 2 MHz */ SystemClock_Config();   /* Configure the system power */ SystemPower_Config();   /* Check and handle if the system was resumed from StandBy mode */ if(__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET) { /* Clear Standby flag */ __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB); }   /* Disable Wakeup Counter */ HAL_RTCEx_DeactivateWakeUpTimer(&RTCHandle);   /*## Setting the Wake up time ##
